 wing with two small semi-diaphanous spots, one at the upper end of cell and

 and in the male sometimes absent ; another outer very minute dot, which 

 also is often absent in the male ; and three larger spots obliquely two 011 

 the disc and one touching the submedian nervure ; hindwing unmarked. 



Underside paler spots as above ; forewing with a blackish longitudinal 

 shade covering the lower half of the wing ; hindwing with an indistinct 

 diffused discal fascia of same colour.

" d* . Upperside both wings dark brown. Forewing with two conjoined 

 spots placed obliquely near the end of the cell, two subapical dots, the 

 lower four times the size of the upper, a quadrate spot in the second 

 discal interspace, two spots in continuation in the submedian interspace, 

 all bright ochreous. Cilia cinereous. Hindwing with a small patch of 

 yellow in the middle of the disc. Cilia ochreous. Underside forewing 

 with the costa narrowly, the apex widely, decreasing rapidly to the angle, 

 bright ochreous, the rest of the wing black ; the spots as above, but the 

 lower of the two in the submedian interspace much larger and diffused, two 

 short dark streaks placed outwardly against the subapical dots, beyond 

 which is a submarginal series of obscure spots of a paler yellow than the 

 ground on which they are placed. Cilia dark brown. Hindwing bright 

 ochreous, with an obscure discal series of dark spots of which one in the 

 upper subcostal interspace is alone prominent. Cilia ochreous defined in- 

 wardly by a fine dark brown line. Antennae with the shaft above fuscous, 

 the anterior half of the club ochreous, the anterior half of the shaft below 

 ochreous. No secondary sexual characters. 



Expanse: & 1-15 inches. 



Marked almost exactly as in Halpe honorei, de Niceville (which 

 however may be an Isoteinon, the male being unknown), from South India 

 but all the spots on the forewing smaller, the one in the discoidal cell nearly 

 divided into two portions, the discal patch on the hindwing less than half 

 the size and the insect itself smaller. 



A single specimen only was obtained from Tavoy.
